SPRING-WHEEL.

Specification of Letters Patent- Patented April 23, 1907.

ful Improvement in Spring-Wheels, of which the following is a specification. My invention relates to improvements in wheels for vehicles, its object being to reduce jar and produce a wheel which shall be simple, cheap and e'llicient. g

The pneumatic tires generally used on vehicles, such as automobiles, are costly and are extremely liable to puncture and other damage, to repair which involves consider- It is to overcome these'objections that I have devised the improvements hereinafter pointed out, and to these ends my invention consists in certain novel features of construction, arran ement and combination of parts as will be iereinafter fully described and pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of my improved wheel. Fig. 2 is a perspective view of the hub. Fig. 3 is an enlarged sectional elevation showing tension device.

My wheel which is composed entirely of steel consists of the hub A having the central opening A within which the box A is secured; the hub near each end is provided with the openings a which are arranged in series of twos and within which are secured the inner ends of spoke sections B; each section B passes through the clamps C, C and then through the collars D, D.

E are outer spoke sections which are secured at their outer ends to the fiexible steel ,rim F and then pass through the collars D and D before mentioned; after passing through the collars D the inrier ends of spoke sections E are bent outwardly and have nuts 5' threaded thereon. The outer ends of spoke sections B after passing throu 11 the outer collars D are also bent outward y and have threaded thereon the nuts I). I

G are coiled springssui'rounding the overlapping portions of the spoke sections B and E between the collars D and D for the purpose of regulating the tension of the springs and truing the wheel. The rim F is made of spring steel and is flexible so that theportion resting on the ground during travel will fiatten and assume the shape ofthe road, the resiliency of the wheel being due partly to the flexibility of the rim and partly to the springs G which surround the overlapping ends of the spoke sections.

As shown in Fig. 3 the outer face of the collars D and D is beveled off where the threaded ends of the spoke sections pass through them.

The clamps C and C may be of any suitable material and construction.

I claim 1. A wheel consisting of a hub and a flexible rim, spoke sections secured respectively in said hub and rim and overlapping each other and coiled springs surrounding the overlapped portions of. the spoke sections.

2. A wheel consisting of a hub and a flexible rim, spoke sections secured respectivelv in said huband rim and overlapping each other at their free ends, collars on-the over lap ed ends of said spoke sections, and

CO1 ed springs surrounding said overlapped portions and abutting against the said colars. 3. A wheel consisting of a hub and a flexible rim, spoke sections secured respectively in said hub and rim, and overlapping each other at their free ends, a collar mounted on each spoke section end of the. other spoke section passes, a coiled spring surrounding the overlapped ends of the spoke sections between the col lars, and adjustable means on the end of each spoke section for regulating the tension of the coiled springs.

4. A wheel consisting of a hub and a flexible rim, s oke sections secured respectively in said hu and rim, the spoke sections secured to the hub being bent to cross each other, clamps securing the spoke sections together at'their crossing points, each spoke section secured -to the rim extending inugargly and overlapping the outer end of one o t e hub spoke sections,-collars on each through which the,

spoke section through which the end of the I00- overlapping spoke section passes, coiled spring surrounding the overlapped ends of the adj'acent spoke sections between'the aforesaid collars, and adjusting nuts on the ends of the spoke sections outside of the collars, for regu- 1o 5 lating the'tension of the coiled springs.
